$y = \frac{\ln (\frac{x}{m} - s a)}{r^{2}}$

Step 1

To write $- s a$ as a fraction with a common denominator, multiply by $\frac{m}{m}$ .

$y = \frac{\ln (\frac{x}{m} - s a \cdot \frac{m}{m})}{r^{2}}$

Step 2

Combine $- s a$ and $\frac{m}{m}$ .

$y = \frac{\ln (\frac{x}{m} + \frac{- s a m}{m})}{r^{2}}$

Step 3

Combine the numerators over the common denominator.

$y = \frac{\ln (\frac{x - s a m}{m})}{r^{2}}$
